Experience has shown that accidents are rarely simple and almost never result from a single cause.
Each incident or accident is a learning opportunity, but one that could be wasted unless theeffort put into analysing it focuses on discovering the true underlying causes of the incidentrather than focusing on the people directly involved and the immediate causes of theirfailure.
Incident investigation is one of the tools for improving control over hazards in theworking environment. It is a retrospectivetool – applied once the flaws in our systemshave drawn attention to themselves via an incident. Any modern organisation may also havein place proactive methods of observation, inspection and audit as complementary methodsfor improving hazard control.
